Biography
Matteo Seita obtained his bachelor degree in Electronic Engineering from Politecnico di Torino (Italy) in 2005. Two years later, he obtained a master degree in Nanotechnology for Integrated Systems, which was jointly awarded by Politecnico di Torino, Grenoble INP (France), and EPFL (Switzerland). During his master he spent six months as a visiting student in the Department of Materials Science and Engineering at MIT (USA), where he wrote his master’s thesis on carbon nanotube synthesis under the supervision of prof. Carl V. Thompson.

In 2012 he obtained his PhD from the Department of Materials Science at ETH Zurich (Switzerland), where he worked in the group of prof. Ralph Spolenak on microstructure control of metal films through ion-irradiation. He then moved back to MIT to work as a postdoctoral associate in the Department of Materials Science and Engineering. Here, he collaborated with professors Michael J. Demkowicz, Chris A. Schuh, and Silvija Gradečak on several fundamental and applied projects with the common overarching theme of characterizing structure-property relationships of metallic grain boundaries.

In October 2016 Matteo joined NTU as an assistant professor at the school of Mechanical and Aerospace Engineering, where he currently leads the Additive Microstructure Engineering Laboratory.

Research
  • Interest:
    Metal additive manufacturing, Microstructure control, High-throughput microstructure analysis, Failure of polycrystalline metallic materials, Non-destructive testing.
  • Projects:
    Layer-wise Engineering of Grain Orientation Distribution (LEGO) in Metal Additive Manufacturing
    We make new metallic materials with complex microstructure by engineering the grain orientation distribution one layer at the time during additive manufacturing.
    [Materials]
    Advanced Metallography: Assessing microstructural-crystallographic information using optical microscopy
    The goal of this project is to develop a technique to assess grain orientation information in polycrystalline metals via numerical analysis of optical micrographs. This work will enable fast and cost-effective microstructure characterization.
    [Materials]
    Measuring grain boundary crystallography-property relations
    We perform high-throughput experiments on polycrystalline metals to assess grain boundaries (GBs) crystallography-property relations. The obtained information will drive the design of metallic materials with improved properties.
